Arista SFP-10G-ER40 Compatible 10GBASE-ER1310 SFP+ Transceiver Module (SMF, 1310nm, 40km, LC, DOM)
This Arista SFP-10G-ER40 compatible SFP+ transceiver supports 10GBASE-ER1310 and 10GBase-EW1310 throughput up to 40km over single-mode fiber (SMF). It operates at a 1310nm wavelength and features an LC duplex connector. Following various industry standards, the transceiver complies with SFP+ MSA, SFF-8431, SFF-8432, and IEEE 802.3ae. That ensures seamless interoperability and flexibility within a multi-vendor network. This singlemode SFP+ module is ideal for 10G fiber connectivity applications, such as SOHO networks, data centers, enterprise wiring closets, large campuses, Metro Area Networks, Remote Radio (RRU), and Baseband Units (BBU). Most importantly, we code and test each module to ensure it works with the 10G SFP+ port of Arista network switches, routers, servers, and network interface cards (NICs).

Key Features
Optimal Performance and Quality for 10G Networks
Featuring a built-in Semtec/Macom chip and reliable DFB laser from global leaders, the 10G SFP+ ER1310 module delivers low power consumption and stable optical links for high-speed single mode networks like 10G Ethernet/Fibre Channel. You can rest assured regarding quality and warranty.

Intelligent DOM/DDM for Reliable Networks
With built-in DOM/DDM function, the 10G SFP+ ER1310 module allows users to monitor the fiber link operating parameters in real-time. It will enable you to troubleshoot when problems occur quickly, ensuring a reliable optical network.

Green Network, Extending Switch Lifespan
High energy consumption and heat generation are significant threats to network stability. Our 10G SFP+ ER1310 transceiver features a low-power design (<1.2W), effectively reducing heat generation and preventing performance degradation caused by temperature increases. And finally, extend the life of your switch and server, and help build a green and efficient 10G network.
